- [Real Transmission Diagnostic vs\. a Quick Code Scan](https://advancedtransmission.com/transmission-diagnostic-vs-code-scan/): A code scan reads what the car's computer reports — useful, but codes identify symptoms, not causes\. A real transmission diagnostic adds a fluid inspection, a road test under load, and a physical drivetrain check, which is how you tell a $90 solenoid from a $4,000 rebuild\. Never approve major work from a code alone\.

Why us: Our free TrueTest™ inspection is the full diagnostic — codes are where it starts, not where it ends\.
- [What Happens If Your Rebuilt Transmission Fails Under Warranty](https://advancedtransmission.com/rebuilt-transmission-fails-under-warranty/): With a comprehensive warranty, you bring the vehicle back \(or to a network shop if nationwide\), the failure is diagnosed, and covered repairs are made at no charge for parts or labor\. The horror stories happen with parts\-only warranties, vanished shops, or undocumented maintenance — all avoidable before you sign\.

Why us: Warranty claims are where shop character shows\. We've been honoring ours in the same community since 1986\.
